An existing building is suffering from cracks in the exterior walls. the investigating engineer wants to ensure that the foundations are not overloaded. the existing columns carry dead live load of 45,000 pounds. the footings are 3 ft 6 in. x 3 ft 6 in. x 1 ft 6 in. thick and rest on sandy soil. the soils report estimates the allowable soil bearing pressure to be 2500 psf. what would be the smallest area for a safe footings are adequate to carry the load?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
